Check that you are using the correct escape characters.
in printerparameter check that you are on auto
else check in the driver you are using esc LF Nul or {'} characters.
last if in serial mode check the communication parameters
default 9600,n,8,1 (no partity 1 stop bit, 8 data bits)

You don't specify the printer model, don't specify the operating system... How can we help you, if you don't help us understand your problem?...

Vaguely (as I don't have any details from you) you need to check the default print settings. In Windows they are located in the printer folder options and in the printer driver settings, and have to be both changed to be sure.

Also you might have documents formatted for A4 paper.Some printers in their settings have an option to automatically substitute A4 for Letter and vice versa, might be worth to find this setting and enable it.
